Product Information
| Description: | Nalidixic acid sodium salt is an inhibitor of bacterial DNA polymerase (DNA gyrase) and avian myeloblastoma virus reverse transcriptase. Nalidixic acid sodium salt is a quinolone antibiotic, it is effective against both gram-positive and gram-negative bacteria. Nalidixic acid acts in a bacteriostatic manner in lower concentrations and is bactericidal in higher concentrations. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
